[PATCH] D113578: [SCEV] Apply loop guards when computing max BTC for arbitrary steps.

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Analysis/ScalarEvolution.cpp:9670
+    assert(MaxWithGuards.ule(getUnsignedRangeMax(E)) &&
+           "applying loop guards unexpectedly pessimized max count");
+    M = getConstant(MaxWithGuards);
----------------
Same as in other cases, this assertions likely doesn't always hold.
